Stranger in a strange land: Ibero-American strain of Mycobacterium tuberculosis in Tibet, China

Interestingly, a drug resistant isolate of the Ibero-American LAM RD-Rio sublineage was recovered from TB patient of Tibetan ethnicity, a resident in the Lhasa district in Tibet. An additional in-depth analysis by whole genome sequencing might help to understand the evolutionary history of this isolate and its possible route to the rural setting of the Tibetan highlands.
